“…On the other hand, some geochemical studies were carried out in precambric rocks from Mexico in the Grenvilliane basement of Huiznopala Gneiss [10], where were obtained positive anomalies of Eu and low concentrations of Y, Zr, Nb, Th and U, similarly to that reported in the Oaxaqueño Complex [11] located in the south east of Mexico.…”

“…In the area of Novillo, the Huiznopala gneiss records an arc magmatism extending from ϳ1200 to 1150 Ma (various U-Pb dates). A later granulite facies metamorphism was probably associated with the emplacement of an anorthosite-gabbro complex at ϳ1000 Ma (Lawlor et al, 1999;Weber and Köhler, 1999). Post-metamorphic, Sm-Nd garnet ages of ϳ933 to ϳ911 Ma and Rb-Sr biotite ages of ϳ882 to ϳ866 Ma (Weber and Köhler, 1999), as well as Rb-Sr biotite ages of 876 and 827 Ma (Patchett and Ruiz, 1987), are reported.…”

“…Southern Grenville Province (central and west Texas into northern Mexico): Mosher (1998) and Rougvie et al (1999). Southern Mexico: Patchett and Ruiz (1987), Ruiz et al (1988), Lawlor et al (1999) and Weber and Köhler (1999). The "belt with Grenvillian-age rocks" of Argentina does not fit with any of these regions; however, the Early Paleozoic sedimentary cover correlation suggests the Southern Grenville Province as detachment site for the basement of the Precordillera or Cuyania terrane.…”

“…There, the different rock exposures have been included in the "Oaxaquia" microcontinent (Ortega-Gutiérrez et al, 1995). The rocks comprise metagranites, amphibolites, mafic and intermediate orthogneisses, paragneisses, marbles, and metaquartzites, that underwent granulite facies metamorphism associated with minor magmatism during the final Grenville deformation at around 1000 Ma (Ruiz et al, 1988;Lawlor et al, 1999;Weber and Köhler, 1999). Among these exposures, a felsic orthogneiss of the Guichicovi Complex yielded a crystallization age for the granitic protolith of 1231^43 Ma and a peak granulite metamorphism age of 975^35 Ma (U-Pb zircon: Weber and Köhler, 1999) from the Maya terrane.…”

The N-S trending belt with Grenvillian-age rocks developed in central western Argentina represents the basement of an allochthonous terrane derived from Laurentia during the Early Paleozoic. The Las Matras pluton (36Њ46 H S, 67Њ07 H W) is located at the southern extension of this belt in the Las Matras Block. It consists of a low-Al tonalitic to trondhjemitic facies characteristic of an arc magmatism. Isotopic studies yielded Grenvillian Rb-Sr (1212^47 Ma) and Sm-Nd (1188^47 Ma) ages which, due to the undeformed and non-metamorphosed character of the pluton, are interpreted to represent a crystallization age of around 1200 Ma. Although this age is slightly older than available dates from other exposures of the same belt, and the undeformed feature is also distinctive for Las Matras, the depleted Sr and Nd isotopic signatures of the pluton agree with those from other magmatic rocks involved in that belt. The differences found between Las Matras and the northern exposures indicate that this belt with Grenvillian-age rocks comprises regions of non-homogeneous evolution. Although the correlation of the Lower Paleozoic platform carbonates from the sedimentary cover of the Grenvillian-age basement rocks suggests the surroundings of the Southern Grenville Province (Texas and northern Mexico) as the probable detachment site for the Argentine belt, comparison of magmatic and tectonic processes involved in these basement rocks does not indicate similar evolutions. This fact can suggest an independent evolution of the Argentine belt prior to amalgamation to the Laurentian Grenville orogen. ᭧

C i e n A ñ o s ResumenLa extraordinaria diversidad magmática de la Faja Volcánica Transmexicana está controlada (directa o indirectamente) por dos placas oceánicas independientes cuyos parámetros geofísicos y composicionales se modifi can constantemente a lo largo de la trinchera, por un régimen tectónico esencialmente distensivo que opera con distinta intensidad sobre la placa continental, por un basamento cortical con diferentes edades, espesores y composiciones, y por una fuente mantélica primaria de composición extremadamente variable que ha sido infl uenciada, en mayor o menor medida, por los agentes químicos derivados de la subducción. El régimen tectónico convergente y, en consecuencia, el arco magmático, tampoco han evolucionado de forma homogénea a lo largo su historia, sino que han mostrado transformaciones notables en su posición, geometría y composición. Por estos motivos, la Faja Volcánica Transmexicana es el resultado de uno de los sistemas tectónicos convergentes más complejos del planeta, el objeto de más de un siglo de investigaciones científi cas, y también el centro de las controversias más notables sobre la geología mexicana.Palabras clave: Faja Volcánica Transmexicana, México, subducción, arco magmático, petrología ígnea, manto, corteza.
